Legacy Effects of Drought in Semi-Arid Ecosystems

What are the legacy effects of drought in semi-arid ecosystems and how are they captured in the ED2 model? This project compares tree core specimens and climate data to define legacy effects, modelling with and editing the ED2 model, and investigating the effects of drought on the composition and structure of the ecosystem.  

This is Jackie Ho's OEB thesis project advised by Paul Moorcroft and Miriam Johnston.
